Passivation Liquid

PASSIVATION LIQUID is an innovative,
concentrated liquid product specifically engineered to passivate
pickled installations and tank surface areas made of austenitic
stainless steel. It provides a protective oxide layer against
corrosion contamination. Furthermore, when it is diluted with water,
it can be safely used to clean aluminum surfaces, aluminum parts and
their metal alloy compounds.

Characteristics, Advantages & Applications

Efficiently binds to pickled austenitic
stainless steel surfaces to deactivate erosive conditions and to
protect against further corrosion.

Can safely be used to clean aluminum
installations, parts and surface areas when diluted with water.

Provides a quick and thorough treatment.

Cannot be used until after the pickling
process.

Non-flammable, non-conductive and
non-toxic.

Has no known effect on rubber or plastic.

May be combined with a specific range of
other products.

No heating is required upon application and
it is water-soluble.

Cost effective, easy to apply and use.

During 1996, chemical tankers were only
permitted to use tank cleaning agents, which had been approved and
evaluated by the International Maritime Organisation (IMO).
PASSIVATION LIQUID was evaluated through IMO’s Working Group on
the Evaluation of Safety and Pollution Hazards of Chemicals (ESPH
Working Group) and found to meet the requirements of paragraph 1.8.2
of the P&A Standards.

Application and Use

A. Dosing Procedure

Stainless Steel Treatment: For this application,
PASSIVATION LIQUID must be used undiluted in quantities proportional
to cover the surface areas or installations under treatment. Note
that 1 litre of the product may cover approximately an area of 12
sq. meters

Aluminum Cleaning: Here, PASSIVATION LIQUID may
be diluted to a 1:1 proportion with water. The quantity of diluted
solution required, corresponds to the area to be covered, the degree
of contamination, the available down time and the desired degree of
cleaning.

B. Procedure

Stainless Steel Treatment: PASSIVATION LIQUID
may be applied by conventional means or by the circulation method.

Conventional methods such as a brush, hard
sponge and or a thick mop can be used when stainless steel parts
and/or components are to be treated. Application should be carried
out for approximately 15 minutes. Afterwards, rinse thoroughly with
distilled water and leave to dry.

Circulation is a method commonly used for
pipeline systems and tanks. Here the system under consideration must
be filled with PASSIVATION LIQUID, which must be circulated for
approximately 2 hours. Then, the system must be drained and rinsed
thoroughly with distilled water. Afterwards, leave the system to
dry. Note that before discarding the liquid, it should be
neutralized with slaked lime.

Aluminum Cleaning: For the cleaning of aluminum
surfaces, pipe systems and parts, any of the cleaning methods for
stainless steel, as described above, can be used. The cleaning time
is approximately for 2 hours. Afterwards, rinse thoroughly with
water.

Note that, neutralization with slaked lime
before draining is also applicable in circulation cleaning
processes.

Important Information

PASSIVATION LIQUID is considered highly
corrosive. Operators must consult the Safety and Handling
instructions table before use.
